Abstract

IMPORTANCE: To study alternative voiding trial (VT) methods after urogynecologic surgery that may potentially decrease catheterization. OBJECTIVE: The aim of the study is to compare voiding assessment based on a minimum spontaneous voided volume of 150 mL with the standard retrograde fill (RF) approach in women after urogynecologic procedures. STUDY DESIGN: Women undergoing urogynecologic surgery were randomized to RF or spontaneous void (SV) groups. Women in the RF group had their bladders backfilled with 300 mL of saline before catheter removal, those in the SV group did not. To pass the VT, patients in the RF group were required to void 150 mL at one time within 60 minutes, and patients in the SV group had to do the same within 6 hours. The primary outcome was the VT failure rate. We also compared the false pass rate, urinary tract infections, satisfaction, and preference of VT method. RESULTS: One hundred nine women were enrolled in the study, 54 had SV and 55 underwent RF. Baseline characteristics were not significantly different other than history of prior hysterectomy. There was no significant difference in procedures between the groups. There was no difference in VT failure rate between the groups-SV (7.4%) and RF (12.7%, P = 0.39). The false pass rate was 0 in each group. Urinary tract infection rates were similar between SV (14.8%) and RF (14.5%) groups ( P = 0.34). Patient satisfaction for VT method was not significantly different. CONCLUSIONS: Spontaneous VT was not superior to retrograde void trial. Therefore, we cannot recommend one method of VT after urogynecologic surgery.CondensationVoiding assessment based on minimum SV of 150 mL is comparable with VT with RF after surgeries for prolapse and urinary incontinence.
